Abstract
Combining multiple subsystems involving biomass processing, biomass gasification of the processed biomass where a synthesis gas is produced then converted to hydrogen fuels or other transportation fuels for use in coupled transportation systems sized to consume all the transportation fuel produced. Carbon in the biomass is converted to CO2 in the conversion process and a portion of that CO2 is captured and sequestrated for long term storage.
Claims16
A method of converting biomass into hydrogen, the steps of the method comprising:
- creating processed biomass from unprocessed biomass aggregated to a central point having a moisture content of 30% to 45% by weight by:
- adding drying heat to a system configured to reduce moisture of unprocessed biomass to 17% by weight;
- filtering out particulates from the unprocessed biomass which exceed a predetermined diameter threshold using one or more of:
- a screen, diverter gate, and disc screener;
- depositing the processed biomass in storage using a lock hopper system and feed lines;
- submitting the processed biomass, pure oxygen, and super-heated steam to a gasification process to create a syngas using internal reaction thermal energy, wherein the syngas comprises predominantly carbon monoxide and hydrogen, in which:
- a portion of the processed biomass is converted to carbon dioxide that is captured and sequestered in a storage tank;
- and
- the hydrogen is produced and captured;
- wherein the syngas is between 600 and 1,000 degrees Celsius;
- gradually lowering a temperature of the syngas using three fixed bed reactors to increase hydrogen content.
